Question

我一直使用单一测试方法运行一个简单的Junit测试类。我遇到了以下错误。

stackTrace如下

java.lang.ExceptionInInitializerError

任何人都可以帮助我背后的原因

我没有必要将任何jar文件添加到CLASSPATH中。我通过添加以下系统属性解决了它：

-Dorg.apache.commons.logging.LogFactory = org.apache.commons.logging.impl.SLF4JLogFactory

是否必须通过JUNit运行Web服务？

运行JUNIT方法时出现java.lang.ExceptionInInitializerError
